A Hybrid Model of a Genetic Regulatory Network in Mammalian Sclera [PDF]
EPTCS 125, 2013, pp. 99-105, 2013 Myopia in human and animals is caused by the axial elongation of the eye and is closely linked to the thinning of the sclera which supports the eye tissue. This thinning has been correlated with the overproduction of matrix metalloproteinase (MMP-2), an enzyme that degrades the collagen structure of the sclera.
